This technique summons a small, gourd-shaped toad, called a "Gourd Toad" (瓢箪蝦蟇, Hyōtan Gama), a unique species of toad indigenous to Mount Myōboku. This technique is used to capture and isolate a victim by dragging them into the toad's stomach. Isolated from the outside world by a barrier, the space inside the Gourd Toad's stomach is far larger than the surface size of the Gourd Toad itself.

The environment inside the toad's stomach is a cavernous chamber, which includes a lake of strong corrosive gastric acid that can dissolve anything that should happen to fall into it, along with shores around the acid lake, and formations sticking out of the lake; the already-existing structures within the Toad's stomach are seemingly unaffected by the acid lake. Once trapped inside, an opponent is cut off from any allies and susceptible to attack, and can then be easily defeated.
